Code Janitor
Arduino AI Agent

An AI coding assistant built for Arduino IDE 2.x. Ask questions, get fixes, refactor sketches, and generate code — all inside your Arduino IDE.

Getting Started

Installation

Install the VSIX plugin into Arduino IDE 2.x in 4 steps.

Note: This is a standalone VSIX plugin for Arduino IDE 2.x. It does not require the main Code Janitor VS Code extension.
1

Download the VSIX

Go to the GitHub Releases page and download the latest code-janitor-arduino-ai-agent-x.x.x.vsix file.

2

Open the .arduinoIDE folder

Navigate to the .arduinoIDE folder on your system:

Windows C:\Users\<YourName>\.arduinoIDE
macOS /Users/<YourName>/.arduinoIDE
Linux /home/<YourName>/.arduinoIDE

If the folder doesn't exist, create it manually. On Windows press Win+R and type %USERPROFILE%\.arduinoIDE to open it directly.

3

Create a plugins folder and place the VSIX inside

Inside .arduinoIDE, create a new folder named exactly plugins. Then move the downloaded .vsix file into it. Your final folder structure should look like this:

📁 .arduinoIDE
    └── 📁 plugins
            └── 📄 code-janitor-arduino-ai-agent-1.2.0.vsix
4

Restart Arduino IDE and open the chat

Fully close and reopen Arduino IDE 2.x. The plugin loads automatically from the plugins folder on startup. Press Ctrl+Alt+A (or Cmd+Alt+A on Mac) to open the Arduino AI Chat panel.
